To shoot tight groups at distance, a load MUST be developed
that is tuned for that individual rifle. What primer to use,
what type and how much powder to use, and what bullet to use
can be very overwhelming. This is a good area to pick brains
with
a reliable custom gunsmith. If your rifle has been accurized,
the gunsmith who accurized it will have valuable suggestions
for where to get started on developing a load tuned for that
rifle. We develop new loads for our rifles using load groups
of 5 shells each at 1/2-grain powder increments. If you are
not comfortable with hand re-loading, do not despair--you can
hire people to reload for you. Choosing the brass and primer
is fairly basic--just make sure you get each item from the
same lot. Choosing powder and bullet has to be determined at
the shooting range. Consult reloading manuals to initially
narrow the choice of bullets you plan on testing. Consult your
gunsmith and knowledgeable shooters, such as bench-rest shooters,
about powder choices. Once you have 2-3 different bullets to
test, and the same number of powders to test, you can hand
load 5 shot groups of each combination, at 1/2 grain increments.
Go to the shooting range, and test fire each 5-shot group,
off good-quality rests or sandbags, with a Clean and Cool rifle.
Find the combo your rifle likes the best, and start dialing
it in,

of powder. The combo your rifle likes best will consistently
have the tightest groups at 100 yards, or any distance.
